other foreign substances with a view of in-' creasing the market valuethereof.

The invention will be fully understood from the following descriptionand claims when the same are considered in connection with theaccompanying drawings, forming part of this specification, in which: I

Figure 1 is a top plan view of the pea separator constituting thepresent and preferred embodiment of my invention. Fig. 2 is a sideelevation of the separator. Fig. 3 is a transverse section of theseparator, taken in the plane indicated by the line 33 of Fig. 1. Fig.4C is a detail longitudinal view illustrative of the inclined sieve, thepea conveyer and the dust-ejecting means of the separator.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is the main frame of my novel separator, which is preferably of woodand open in construction, and B and C are rear and front axles withwhich the frame is preferably, though not necessarily equipped, and uponwhich it is mounted. These axles B and C may be of the ordinaryconstruction or of any other construction compatible with the purpose ofmy invention without involving a departure from the scope thereof, andare designed to be equipped with suitable traveling wheels (not shown)so as to permit of the machine being conveniently hauled from place toplace. The rear axle B may be connected to the frame A in any convenientmanner. The front axle C, however, I prefer to connect to the framethrough the medium of a fifth wheel a and a king bolt 6, as shown, inorder to permit of the machine being readily guided while en route fromone point to another.

D is a screen fixed over the main frame A at the top thereof and havinglarge meshes as shown. This screen is preferably formed of longitudinalwires and transverse wires stretched taut over the longitudinal wires,and it is preferably divided into three equal parts by cross bars Ddisposed above the transverse wires and interposed between the sides ofthe main frame A so as to lend strength to the upper portion of thesame.

E E, Fig. 3, are longitudinal rails, preferably of steel, fixed to theinner sides of the side walls of the main frame A.

F F are transverse shafts journaled in suitable bearings in the mainframe A at the ends thereof and bearing sprocket wheels 0..

G G are sprocket belts mounted on the wheels 0 of shafts F and F andarranged parallel to and at the inner sides of the side walls of themain frame.

HH are transverse finger bars fixedly connected to'the chains G atintervals in the length thereof and having anti-friction rollers ofarranged to bear and travel on the rails E and I I are fingers carriedby the bars H and having their free portions, indicated by c, bentforwardly with reference to the direction in which the upper stretchesof the sprocket belts G are driven in practice. The rails E are soarranged, relative to the screen D that in their forward movement,indicated by arrow in Fig. 1, the bent ends 6 of the fingers I travelquite close to the underside of' the screen D. From this it follows thatwhen a mass of pea-bearing vines is thrown by hand or otherwise on thescreen D, and the peas extend down through the interstices of saidscreen, the traveling fingers I will engage and pull the peas from thevines, and cause the same to drop in the frame.

J J are sieves, of reticulated or other suitable material, fixed in theframe A below the endless pea-pulling means described in the foregoing.The said sieves extend throughout the length of the main frame A, Fig.4, and decline toward the longitudinal center of the machine, Fig. 3,for a purpose which will be presently apparent.

K is a pea conveyer. This pea conveyer comprises a longitudinal opentrough L disposedbetween and adapted to receive from the transverselydeclined sieves J and having an upwardly reaching forward arm M and alsohaving a perforated bottom N adapted to discharge dust, dirt and thelike, a rear transverse shaft P bearing sprocket wheels f, a forwardtransverse shaft Q bearing sprocket wheels 9 and an additional sprocketwheel 71,

Fig. 1, lower and upper anti-friction and guide wheels k and Z carriedby the trough L, sprocket belts R passed around the sprocket wheels fand g and having their lower and upper stretchesarranged to bear on thelower and upper wheels 76 and Z, respectively, and transverse, pendentblades S fixedly connected to the belts R and arranged to travelforwardly in the trough L and its arm M and rearwardly below said arm Mand trough L, as illustrated. The sprocket belts R derive motion fromthe shaft F through a sprocket wheel m thereon, Fig. 1, the shaft Q, anda crossed sprocket belt T connecting the wheel m and the sprocket wheelh on the shaft Q.

In addition to the features mentioned in the foregoing, the trough L ofthe pea conveyer K is provided with inwardly directed flanges L Fig. 3.These flanges L have for their function to prevent dust, dirt etc. fromfalling on the belts which bear the blades S, and the wheels supportingthe upper stretches of said belts.

U is a chute arranged to receive peas, dirt and trash from the upper endof the trough arm 1V1. I

V is a fan casing having a discharge conduit W provided in its upper andlower walls with alined openings 10 and 112 the upper opening w beingarranged to receive from the chute U.

U is a chute arranged to receive from the lower opening w in thedischarge conduit W of the fan casing V and discharge into a receptacleplaced to receive peas.

X is a transverse shaft journaled in the side walls of and extendingthrough the easing V, and Y is a fan fixed on the shaft X and designedto be rotated at a high rate of speed. When the fan Y is rotated asstated, and peas, trash and dirt are discharged into the upper openingto of the discharge conduit W of the fan casing V, it will be apparentthat the peas will gravitate through the said conduit V and the opening0.0 in the lower wall thereof, and from thence will pass to and throughthe chute U into a receptacle placed to receive the same. The dirt andtrash, however, will be separated from the peas in the conduit W andwill be forced out of said conduit by the blast from the fan Y. Fromthis it follows that when the peas reach the chute U they will be in aclean and wholesome condition ready for market.

The shaft F is provided with a band pulley 76 designed to receive a band(not shown) from a steam en ine or other motor, and motion is preferab ytaken from said shaft F to drive the fan Y, the driving connectionscomprising a sprocket wheel 1" on shaft F, a counter-shaft Z suitablymounted on the main frame A, small and large sprocket wheels 8 and t onsaid counter-shaft, a sprocket belt u connecting the wheels 1 ands,

a small sprocket wheel v on the fan shaft X, and a sprocket belt wconnecting the sprocket wheel 15 and the said sprocket wheel 7).

It will be gathered from the foregoing that when the shaft F is rotated,the several working parts of my improved machine will be put in motion;also, that when pea-bearing vines are deposited on the screen D, thedepending peas will be pulled from the vine by the fingers I and causedto drop on the sieves J. The said sieves declining toward thelongitudinal center of the machine, it follows that the peas etc.received on the sieves will pass to the trough L along which the samewill be carried by the blades S. During the passage of the peas etc.over the sieves J and along the trough L a portion of the dirt and dustwill be separated from the peas, while when the peas etc. drop throughthe discharge conduit W of the fan casing V the peas will be entirelyfreed of dirt and trash with the result that the peas discharged fromthe chute U will be in a clean and marketable state.

Subsequent to the disconnection of the peas from their vines, the vinesmay be removed from the screen D by hand or by any means suitable to thepurpose.

It will be readily apparent that my novel machine is possessed of largecapacity, and is adapted to separate peas from their vines and free thepeas of sand, dust and dirt Without breaking or otherwise deterioratingthe peas.

The machine shown and described is a power machine, but it is obviousthat my improvements may be embodied in a hand machine without involvingdeparture from the scope of my invention as claimed; and in thisconnection I desire to say that in practicevarious changes andmodifications may be resorted to without affecting the spirit of myinvention.

Having described my invention, what I claim and desire to secure byLetters Patent, is: I

1. In a separator, the combination of a screen for supporting pea vines,a plurality of fingers movable be ow and adjacent to the underside ofthe screen and adapted to engage the vines and pull peas therefrom, asieve arranged beneath said fingers, and a trough located to receivepeas from the sieve and having openings in' its bottom.

2. In a separator, the combination of a screen for supporting pea vines,means located below the screen for pulling peas off the vines, inclinedsieves arranged-to receive said peas, a trough dis osed between andarranged to receive peas mm the sieves and having openings in itsbottom, blades arranged to move peas along the trough, and means formoving the said blades.

3. In a separator, the combination of a screen for supporting pea vines,a plurality of fingers movable below and adjacent to the underside ofthe screen and adapted to en gage the vines and pull peas therefrom;inclined sieves arranged to receive said peas, a trough arranged betweenand adapted to receive peas from the sieves and having openings in itsbottom, and means for moving peas along the trough.

4. In a separator, the combination of a screen for supporting pea vines,means located below the screen for pulling peas from the vines, inclinedsieves arranged to receive said peas, a trough arranged between andadapted to receive peas from the sieves and having an upwardly reachingarm at one end and also having openings in its bottom, means for movingpeas etc. along said trough, a chute arranged to receive peas etc. fromthe upper end of the arm of the trough, a

blower, and a casing containing the blower and having upper and loweropenings for the passage of peas; the upper opening being arranged toreceive from the said chute.

In testimony whereof I affix my signature in presence of two witnesses.
